image-crop

A composable image-cropping UI built on react-image-crop. It reads a File, supports freeform or aspect-ratio cropping, generates a PNG data URL, and exposes apply and reset controls.

Installation

pnpm dlx shadcn@latest add @kibo-ui/image-crop

Requires @kibo-ui in the registries of your components.json (shadcn adds official directory namespaces automatically).

Usage

usage.tsx
import { ImageCrop, ImageCropApply, ImageCropContent, ImageCropReset } from "@/components/kibo-ui/image-crop";export function ImageCropExample({ file }: { file: File }) {  return (    <ImageCrop file={file} aspect={1} onCrop={(croppedImage) => console.log(croppedImage)}>      <ImageCropContent />      <div className="flex gap-2">        <ImageCropReset aria-label="Reset crop" />        <ImageCropApply aria-label="Apply crop" />      </div>    </ImageCrop>  );}
  • Profile avatars, cover images, and thumbnail editors.
  • Upload flows that require a fixed aspect ratio or maximum output size.
  • Interfaces where crop content and controls need to be composed independently.
  • Legacy integrations that still use the exported Cropper component.

Examples

Square avatar crop

Use a fixed one-to-one aspect ratio and receive the generated PNG data URL.

square-avatar-crop.tsx
import { ImageCrop, ImageCropApply, ImageCropContent } from "@/components/kibo-ui/image-crop";export function AvatarCrop({ file }: { file: File }) {  return (    <ImageCrop file={file} aspect={1} onCrop={(image) => console.log(image)}>      <ImageCropContent />      <ImageCropApply aria-label="Apply avatar crop" />    </ImageCrop>  );}

Freeform crop with reset

Allow any crop shape and provide a reset action that restores the initial centered selection.

freeform-crop-with-reset.tsx
import { ImageCrop, ImageCropApply, ImageCropContent, ImageCropReset } from "@/components/kibo-ui/image-crop";export function FreeformCrop({ file }: { file: File }) {  return (    <ImageCrop file={file} onCrop={(image) => console.log(image)}>      <ImageCropContent className="rounded-lg" />      <div className="flex gap-2">        <ImageCropReset aria-label="Reset crop" />        <ImageCropApply aria-label="Use cropped image" />      </div>    </ImageCrop>  );}

Custom crop controls

Use asChild to attach crop behavior to custom buttons or other button-like elements.

custom-crop-controls.tsx
import { ImageCrop, ImageCropApply, ImageCropContent, ImageCropReset } from "@/components/kibo-ui/image-crop";export function CustomCropControls({ file }: { file: File }) {  return (    <ImageCrop file={file} aspect={16 / 9}>      <ImageCropContent />      <ImageCropReset asChild>        <button type="button">Start over</button>      </ImageCropReset>      <ImageCropApply asChild>        <button type="button">Save crop</button>      </ImageCropApply>    </ImageCrop>  );}

API reference

PropTypeDefaultDescription

ImageCrop.onCrop(croppedImage: string) => void—Called when the apply action generates a cropped PNG data URL.
ImageCrop.childrenReactNode—Content rendered inside the ImageCrop context provider, normally ImageCropContent and control components.
ImageCrop.onChangeReactCropProps["onChange"]—Optional react-image-crop change callback. The component also updates its internal percent crop state.
ImageCrop.onCompleteReactCropProps["onComplete"]—Optional react-image-crop completion callback. The component also stores the completed pixel crop for applying.
ImageCrop ReactCrop propsOmit<ReactCropProps, "onChange" | "onComplete" | "children">—All other react-image-crop props, including aspect, min/max dimensions, locked, disabled, circularCrop, keepSelection, ruleOfThirds, crop, and related crop configuration.

ImageCropContent.classNamestring—Additional class names merged with the default max-h-[277px] max-w-full classes.
ImageCropApply.asChildbooleanfalseRenders the child through Radix Slot instead of the default shadcn Button.
ImageCropApply button propsReact.ComponentProps<"button">—Standard button properties, including children, onClick, aria attributes, className, disabled, and type. The apply operation runs before the supplied onClick callback.

Cropper.fileFile—Source image file for the backward-compatible Cropper wrapper.
Cropper.maxImageSizenumber5 * 1024 * 1024Maximum output PNG size in bytes, forwarded to ImageCrop.
Cropper.onCrop(croppedImage: string) => void—Receives the generated cropped PNG data URL.
Cropper.onChangeReactCropProps["onChange"]—Optional crop-change callback.
Cropper.onCompleteReactCropProps["onComplete"]—Optional crop-completion callback.
Cropper.styleCSSProperties—Style forwarded to ImageCropContent.
Cropper.classNamestring—Class name forwarded to ImageCropContent.
Cropper ReactCrop propsOmit<ReactCropProps, "onChange">—Other react-image-crop props forwarded to ImageCrop; onChange is redefined by Cropper.

Accessibility

  • The default apply and reset controls are buttons and accept standard keyboard interaction and button attributes.
  • Add an explicit aria-label when using the default icon-only controls, because their default icon children do not provide a visible text label.
  • When using asChild, provide a semantic button element or another accessible interactive element and preserve its keyboard behavior.
  • The rendered image currently uses the fixed alt text "crop"; provide surrounding context or adapt the source if a more descriptive accessible name is required.
  • Use the ReactCrop keyboard and pointer interactions together with visible focus styles; the component maps its focus color to the shadcn primary color.
